The Sigma 120-300mm f2.8 DG OS HSM Lens is designed for the professionals who require versatility, superior performance and a fixed, wide aperture for shooting at dusk. The Sigma 120-300mm offers a unique focal length to ensure you don’t miss a shot, which is crucial for professional sports and wildlife photographers. The HSM (Hyper Sonic Motor) delivers high AF and extremely quiet performance. Full time manual focus override is another key feature that leaves the professional touches in the photographer’s hands. The OS (Optical Stabiliser) makes it possible to use shutter speeds approx. 4 stops slower than would otherwise be possible and enables hand held tele-photography. The Sigma 120-300mm is ready for the toughest photographic conditions and has been designed for exceptional resistance to dust and water. This lens incorporates two FLD (F Low Dispersion) glass and one element made of SLD (Special Low Dispersion) glass, which helps minimise chromatic aberration.
A professional 300mm F2.8 telephoto with powerful zoom capability, this lens allows complete customization, so you can tackle tough situations with ease.
Offering excellent image expression and a low F-number, the large-aperture 300mm F2.8 lens is a favorite piece of equipment among professional photographers. With the idea of taking this spec to the next level with powerful zoom capability, Sigma developed the 120-300mm F2.8 zoom lens. It is difficult to compose shots with traditional 300mm lenses. In the case of sporting events, performances on stage and other situations in which it is difficult to change your position, you often lose the desired shot in the process of changing lenses. A large-aperture 120-300mm F2.8 zoom lens, however, eliminates the need for most lens changes, allowing the photographer to adjust zoom and easily achieve the desired framing. Even in the most difficult of situations, this lens truly empowers photographic expression
Enhanced usability in every way
This lens features durability that stands up to challenging photographic situations and hard use demands along with the intuitive and enjoyable usability that photographers need. Since the lens uses Sigma's inner focus and inner zoom technologies, adjusting the focus and zoom rings does not change the length of the lens, resulting in excellent hold for the selected ring positions. Since the front of the lens does not move, the lens is compatible with a circular polarizer. In every way, Sigma has designed the lens for exceptional usability. The zoom ring is textured to allow fingers to find the correct position easily. Designed for seamless integration with the rest of the lens, the four control switches feature carefully placed lettering and buttons and specially shaped screws. The lens hood has also been completely redesigned, even down to the screws that connect it to the lens, and the newly designed tripod collar provides for connection to a camera strap.
A powerful tool for handheld photography of distant subjects Optical Stabilizer
This lens features Sigma's proprietary OS (Optical Stabilizer) featuring correction of approximately four stops. Thanks to this technology, the lens is a powerful ally to photographers shooting distant subjects without a tripod. Two OS modes are available: Mode 1 for regular photography, and Mode 2 for use in shooting motorsports and other situations in which subjects are moving quickly. By connecting the lens to the separately sold USB dock, users may adjust OS function in detail
TSC (Thermally Stable Composite)
Conventionally it is considered essential to leverage the qualities of metal and polycarbonate in camera and lens layout design. A first for the industry, the barrel of the new series of Sigma lenses features a new TSC (Thermally Stable Composite)* that offers minimal thermal shrinkage combined with exceptional hardness. It also offers 25% greater elasticity than polycarbonate. Since its thermal shrinkage is low, TSC matches well with metal parts, further contributing to the high-precision construction of the lens.
Designed for exceptional resistance to dust and water
This lens is ready for all the tough situations that pros encounter. The mount connection area, manual focus ring, customization switch and other controls, switch panels and cover connection areas are all designed to be dust and water-resistant. The zoom and focus rings are also designed for exceptional usability in real-world circumstances.
Rivaling a fixed focal length lens in image quality
Offering excellent image expression and a low F-number, the large-aperture 300 mm F2.8 lens is a favorite piece of equipment among professional photographers. While taking this spec to the next level with powerful zoom capability, Sigma has also used two lens elements made of fluorite-equivalent FLD (“F” Low Dispersion) glass and one element made of SLD (Special Low Dispersion) glass, which help minimize chromatic aberration and provide image quality that rivals that of a fixed-focus lens.
Exclusive low-dispersion glass
The degree to which light is refracted by glass depends on the light's wavelength. This fact causes different colors of light to focus at slightly different points. The result is chromatic aberration, the color fringing that is particularly noticeable in telephoto lenses. Most chromatic aberration can be removed by combining a high-refractivity convex lens element with a low-refractivity concave element. Yet residual chromatic aberration known as “secondary spectrum” may still remain.To minimize this secondary spectrum, which can be a serious issue with conventional lenses, Sigma lenses feature up to three types of exclusive low-dispersion glass offering superior performance: ELD (Extraordinary Low Dispersion), SLD (Special Low Dispersion) and FLD (“F” Low Dispersion). In particular, FLD glass offers ultra-low dispersion in combination with high transmittance and the anomalous dispersion characteristics of fluorite. Meticulous deployment of these types of exclusive low-dispersion glass and optimization of power distribution gives Sigma lenses superlative image rendition undiminished by residual chromatic aberration.
